This invention relates to fastening devices and more particularly. toxfasteningdeviceszof the zipper typein which the two. portions of the, zip.- perrmay be interlocked or meshed: and inwhich when desired one portion may be doubled in order that specific elements thereof may be interlocked or meshed with one another to form in effect a second fastening device. Fastening devices of this type are highly desirable in many uses, for example, in the manufacture of garments to secure a lining to a shell to permit the assembly to be worn as a unit or as sepa rate elements as desired, as more particularly described and claimed in the co-pending application of Albert Fitch, Serial No. 160,980, filed May 9, 1950, now matured into Patent No. 2,594,259, dated April 22, 1952. g

The chief object of the present invention is to provide a fastening device of the zipper type in which one portion of the zipper may be doubled upon itself and employed to form a second fastening device.

An object of the invention is to provide a fastening device consisting of two series of symmetrical teeth capable of intermeshing, and a reversible slide member adapted to interlock the two series, the teeth of one series being reversible so that such series may be doubled upon itself, the slide member being employed to interlock the teeth of that series with one another. Other objects of my invention will be readily perceived from the following description.

This invention relates to a fastening device of the zipper type which comprises in combination a series ofsymmetrical teeth mounted upon a support, a pin at one end of the series, a second pin at the opposite end of the series, a second series of symmetrical teeth mounted upon a second support to interlock with the first series to form the fastening device, a third pin at one end of the second series, a stop at the opposite end of the series, and a reversible slide member carried on the first support adapted to interlock the two series of teeth. The first series may be doubled and the slide employed to interlock the teeth of such series if desired.

The attached drawing illustrates a preferred embodiment of my invention, in which:

Figure 1 is a plan view of the fastening device in which the two portions of the device are not interlocked;

Figure 2 is a plan view similar to Figure 1 in which the portions of the device are interlocked;

Figure 3 is a plan view illustrating one portion of the device doubled upon itself with the teeth of" that portion. being" interiocked with: each. other:

Figure 4 is. anexaggerateth view. of, the: teeth; of the-fastening: device and Figure- 5 is a. view: in. elevation of; the slide member.

Referring to the drawing there is shown the fastening device of my invention which includes a first portion 2 comprising a series of reversible symmetrical teeth 3 mounted on a tape 4. A pin 5 is disposed at one end of the series and a pin 6 is disposed at the opposite end of the series. A second portion 1' which includes a second series of symmetrical teeth 1 is mounted on a second tape 8. A pin 9 is placed at one end of the second series and a stop I0 i placed at the opposite end of the second series.

A reversible slide member l l carrying pulls l2 and I3 on its opposite sides is mounted on tape 4 and serves to interlock or intermesh the teeth 3, 1 as shown in Figure 2, to form the fastening device.

The series of reversible symmetrical teeth 3 may be doubled as shown in Figure 3 and slide H employed to interlock or mesh teeth 3 with one another to form what is in effect a second fastening device. This is of great value in applications where portions 2 and 1' are employed to join two sections of material to one another and in which it is desired to use portion 2 for example to secure one of the two sections in closed relation.

Considering the present fastening device as employed to secure a liner and a shell to form a garment, tape 4 may be secured to the liner and tape 8 may be secured to the shell. The liner may be secured in place by interlocking teeth 3 with teeth! by means of slide H thereby fastening the liner in place in the shell. If it be desired to employ the liner as a garment alone, the reversible symmetrical teeth 3 may be interlocked and meshed by reversible slide II as shown in Figure 3.

The present invention provides a simple economical fastening device which may be employed in garment construction to securely hold a liner to a shell and which may also be employed to close the liner to form a single garment if desired? The teeth of the zipper type fastening device are symmetrical and reversible and a reversible slide is employed to permit the separate fastening constructions to be employed thus reducing the cost of garments in which the present device is employed for fastening purposes.

While I have described a preferred embodiment of the present device it will be understood the present device is not limited thereto since it may be otherwise embodied within the scope of the following claims.

I claim:

1. In fastening devices, the combination of a series of symmetrical teeth mounted upon a tape,

a pin at one end of the series, a pin'retainer memher at the opposite end of the series, a second series of symmetrical teeth mounted upon a second tape to interlock with the first series to form the fastening device, a second pin at one end of the second series, a stop at the opposite end of the second series, and a reversible slide member movably attached to one end of the first tape adapted to move longitudinally of the tape toward the opposite end to interlock the two series of teeth, the first series of symmetrical teeth being reversible to permit doubling of the series to permit the :pin to be inserted through the slide member and into the retainer member when the slide member is adjacent the retainer member whereby the teeth of the first series may be interlocked by movement of the slide member.

2. Infastening devices, the combination of a series of symmetrical teeth mounted upon a tape, a pin at one end of the series, a pin retainer member at the opposite end of the series, a second series of symmetrical teeth mounted upon a second tape to interlock with the first series to form the fastening device, a second pin at one end of the second series, a stop only at the opposite end of thesecond series, and a single reversible slide member only movably attached to one end of the first tape adapted to move longitudinally of the tape toward the opposite end to interlock the two series of teeth, the first series of symmetrical teeth being reversible to permit doubling of the series to permit the pin to be inserted through the slide member and into the retainer member when the slide member is adjacent the retainer member whereby the teeth of the first series may be interlocked by movement of the slide member.
